Prevent other users in using a certain tag

[Momiji]

Hi Everyone,

I'm not sure if this possible. Let's say I have a tag [label] named 'Tag Ex'. Only specific groups are allowed to use this. Is it possible that when a user (that is not a member of the specific groups) tries to apply the said tag to an incident, an error will appear preventing the user to use the tag?

Thank you!

Hi @Momiji ,
Out of the box, ServiceNow does not support displaying an error when a user applies a specific tag if they are not part of an allowed group.

However, you can effectively restrict tag usage by controlling tag visibility:

Steps:

1. Navigate to System Definition → Tags
2. Open the tag “Tag Ex”
3. Set Viewable by to Groups and Users
4. Select the groups that are allowed to use the tag

Result:

• Users who are not members of the specified groups will not see “Tag Ex” in the tag picker
• Since the tag is not visible, they cannot apply it
• No error message is shown because the tag is simply unavailable

👉 This is the recommended best practice and requires no customization.

Hi @Momiji ,

You may add a before Business Rule on table label_entry to prevent inserting a record when

label_entry.label is 'Tag Ex'

and 

label_entry.table is 'incident'

and

current user is or is not...

then

setAbortAction(true)

Please let me know should you need more details.
